SPECIFICATION forming part of Letters Patent No. 339.724, dated April 13, 1886,

Application tiled April 30, 1885. Serial No. 163,982.

.T0 @ZZ whom it muy concern:

Be it known that l, THOMAS D. XVORRALL, a citizen of the United States, residing at fashington, in the District of Columbia, have in vented certain new and useful lmprovementsin lype\Vi'itiixg and Matrix-Making Machines, ol' which the following is a speciiication, reference being had therein to the accompanying drawings.

y invention relates to improvements in type-writing machines.

The object ofmy invention is to eonnectthe impression key or keysof a type-writing machine with a lever adapted to be operated to bring the type into printing contact with the paper by means of a treadle and footpower.

Referring to the drawings, Figure lis a front elevation of my machine, showing the operating-lever and the treadle for moving the same. Fig. 2 is a detached sectional view. Fig. 3 is a rear view of a portion ofthe operating-lcver and the operating and retaining pawls. Fig. 4 is atop or plan view of my improved machine.

Aindicates the frame ofthe machine, mounted on suitable supports, in any convenient manner.

C is a bracket or cross bar secured to the top of the frame A, in which the type-carrying disk is suspended above the paper-carry ing table, and capable of being readily moved around on its axis or support by taking hold oi' the knobs E 1i] to bring the proper type or letter under the impression-key.

F is a lever pivoted at one end to the post G, said post being secured to the frame A.

H is a bolt or bar secured to the lever F, the lower end ol' which passes through a lug or staple, a, and is provided with a screw-nut, b, at its lower end.

I is aspiral spring, which surrounds the bolt H, the upper end of which impinges against the head c of the bolt, while the lower end of said spring rests on the upper side of the lug or staple a.

By this construction it will be noticed that the lever F is steadied and guided in its upward and downward movement, while the tension of the spring can be adjusted by the screw-nut b to return the lever to a raised or (No model.)

elevated position and ready to bring the next letter into printing contact with the paper.

As a further safeguard, and to insure a true upward and downward motion ofthe lever, so as to bring the impression-keys squarely down onto the type-pins I secure to the under side of the lever F the bar or pina, and adapt it to Work snugly within the socket b, secured to the frame of the machine.

The outer end of the lever F is connected to the treadle K by means of the rod L, and by this means the lever is worked up and down to bring the impression-keys in Contact with the type-pins, and also to move the papercarriage by the foot of the operator, a spiral or other suitable spring, M, being arranged in any convenient manner to return the treadle K to an elevated position.

N is an arm or bar attached to the lever F, in which are secured the impression-keys O, said keys being vertically adjustable in said bar by means of the screw-threads on said keys, to adapt them to impinge on the typepins P, of different lengths, as occasion may require.

R is an adjustable screw-bolt secured in the bar N, the lower end ot' which is adapted to impinge on the upper edge of the pawl-lever S, said pawl-lever being pivoted at one end to the frame A, While the other end is operated upon by a spiral spring, d, which returns the pawl-lever to an elevated position.

The pawl-lever S is provided with an operating-pawl, T, which engages with a rack-bar, U, on the paper-carriage, and when the lever is depressed moves the paper-carriage V forward one or more notches, to space the distance between the letters, the carriage being held iu its forward or advanced position by the retaining-pawl W.

A' is a lever pivoted in the frame of the machine, and is connected to the retainingpawl Vif by means ofthe bolt e, which passes through a slot, f, in the frame A, and by which means the pawl W' can be held out of engagement with the rack-bar.

The operating-paw! T is held out of engagement with the rackbar by means of the lock or latch g, the arm g' of said pawl being pushed back, and the latch g turned around, so as to hold the pawl T ont of` engagement with the rack-bar, thus permitting the paper-carriage to be drawn back to form a new line of printing by the action of a spring,in the usual manner.

The throw ot' the pawl lever to move the papenearriage the proper distance for spacing letters of dilferent size is effected in the following manner. As beforeindicated, the bolt R is screw threaded, and is adjustable in the arm N, and in order to space for small or narrow letters the bolt R is raised or screwed up, so it will impinge but slightly on the pawllevel' S bet'ore the impression is made, thus moving the paper-carriage forward one notch or tooth. Vhere spacing for wide letters is required, the bolt R is screwed down, so it will come in contact with the pawl-lever and force it down farther than in spacing for narrow letters, thus moving the paper-carriage forward two or more notches, as occasion may require. The spacing of the letters may also be effected by having the bolt R rigidly attached to the bar N, and by bringing the lever F in contact with a stop-pin adapted to be adjusted in the perforated bar B'. This will limit the movement ofthe lever F, and bring the pin or bolt R more or less in contact with the pawl-lever. A further adjustment to etlect the throw of the lever F may be made by securing the lower end ot' the rod L to the different staples or fastenings 1 2 3 of the treadle K. The paperbed is moved forward to etl'ect the spacing between the lines by means of the screw-shaft C', working in bearings in the side ofthe frame, and connected to the papenbed D' by the half nut E'. This construction enables me to lift the paper-bed out of engagement with the screw on the shatt C', and to readily bring the paper-bed into position for printing a new page.

It will be noticed that alter the proper type has been brought under the impression-key O, which is the printing center, the papeucarringe is moved forward, and the impression made by the type by the downward motion of the lever F operated by foot-power. This enables me to bring the type in contact with the paper or other material to be printed upon with considerable force, and permit oi' a large number of carbon copies being taken at once or in the one operation.

In practice I may reverse the operation of moving the paper-earriage-i. e., I may form the impression by the downward motion of the lever F, and arrange the operating parts so that the paper-carriage will be moved by the return or upward movement of the lever F.

The type-carrying disk or segment thereof suspended over the paperbed, the adjustable impression pin or key, the type-carrying pins of different lengths, and theadjustable pin for operati ng the pawl-lever are shown,deseribed, and claimed in an application tiled by me April 18, 1885, Serial No. 162,279, and to such features I lay no claim in this application.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. In a type-writing machine, a disk carrying a plurality of rows of type-pins, in combination with a lever operated by a treadle and carrying an arm in which are arranged a plurality of impression keys to impinge on the type-pins, as set forth.

2. In a typewriting machine, a lever pivoted to the side of the lnachine and adapted to be operated by a treadle, as described, said lever being provided with an arm carrying adjustable impression-keys, in combination with type-pins, pawllever, and carriage-rack, as set forth.

3. In a type-writing machine, a pawl for engaging the raek-bar ol' the paper-carriage, in combination with a treadle-lever which operates the typepins to form the impression, the throw of' said lever being adjustable, substantially as described, to regulate the spacing of the letters.

4. In a type-writing machine, the impressionlever F, paper-carriage, and connections, as set forth, in combination with the perforated bar B', and a suitable stop-pin inserted in said bar, whereby the throw ot' the lever is adjusted to move the papercarriage more or less to space the letters.

In testimony whereof I altlx my signature in presence of two witnesses.

THOS. D. VVORRALL.
